Rotary stamping oblique flow centrifugal combined gas compressor and application thereof

The invention provides a rotary stamping oblique flow centrifugal combined gas compressor and application thereof, and belongs to the technical field of turbine engines, the rotary stamping oblique flow centrifugal combined gas compressor comprises an outer casing structure, an inner casing structure, a working mechanism and a diffusion mechanism, the outer casing structure and the inner casing structure are rotary bodies, the inner casing structure is located in the outer casing structure, and the working mechanism is located in the outer casing structure. The inner casing structure and the outer casing structure form a working cavity, and the working mechanism is installed in the working cavity and used for pressurizing airflow. Compared with a compression mode of a conventional combined compressor, a supercharging mode of a supersonic air inlet channel is used for reference, the Mach number of airflow relative to a rotating impeller reaches 2 or above through high-speed rotation, and at the moment, a serie
